Semantic recommender system for Malaysian tourism industry / Tirad Mohammed Aref Almalahmeh
Get PDFSemantic Malaysian Tourism Recommender System (SMTRS) adopts the natural
language interface, recommender system and semantic technology to analyse users’
query and provide answers from the Malaysian tourism domain based on the tourists’
preferences. Tourists usually search for information through different search engines.
However, as found by various researchers the retrieved answers have two main
problems: overloaded and not-related answers. A Recommender System (RS) is one
application that can provide personalized information, with the optimal goal of
providing personalized information recommendation in order to customize the World
Wide Web (WWW). Regular RS users query the system by choosing from a fixed set of
attributes represented by option sets or dropdown lists. Menu-driven navigation and
keyword search currently provided by most commercial sites have considerable
limitations because they tend to overwhelm and frustrate users with lengthy, rigid, and
ineffective interactions. This research proposes incorporating semantic technology with
a recommender system to deliver information that is more related to the tourists’
interests. At the same time a User-friendly Natural Language Interface is also included
to assure convenient query access to the Semantic Web data, where the Natural
Language Interfaces are perceived as the most acceptable by end-users. The approach
results in a prototype with an architecture consisting of a Content-based Recommender
System, Semantic Technology, ontology engineering in the Malaysian Tourism domain,
and Natural Language Interface. This research found, users are satisfied with the
proposed services giving it an excellent rating based on the System Usability Scale

Novel method for assessing basophil activation by measuring altered expression of membrane-bound and intracellular basogranulin stores
No full textBackgroundBasophil activation tests can provide valuable information on allergic sensitivity to a range of different allergens. The most widely employed methods involve flow cytometric detection of increased expression of membrane-bound CD63 or CD203c following addition of allergen to basophils in vitro.The identification of basogranulin, a unique basic protein stored in basophil granules, has opened the way for new basophil activation methods to be explored.MethodsBlood was collected from healthy subjects and patients with a history of allergy to food, drugs, house dust and grass pollen. Basophils were stimulated with specific allergen, anti-IgE antibody, or the peptide f-met-leu-phe (FMLP). Flow cytometry was performed with non-permeabilised and permeabilised cells with antibody specific for basogranulin (BB1) or CD63, and data analysed with CellQuest software.ResultsFlow cytometry with permeablised cells indicated depletion of intracellular stores of basogranulin following basophil activation. Associated with basogranulin release was the presence of increased quantities of this marker on the basophil membrane following cellular activation. Increased membrane expression of basogranulin mirrored that for CD63; and with allergens and other stimuli tested the measurement of cell surface basogranulin represented a more sensitive means for assessing basophil activation in vitro. The flow cytometric assays for basogranulin were optimised for use with samples of whole blood so as to avoid the need for basophil purification.ConclusionsThe rapidity, simplicity and sensitivity of basogranulin-based methods for measuring basophil activation will facilitate their application to clinical samples and allow better assessment for allergic sensitivity
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
